An antiserum against human epidermal keratins was used to detect keratins in frozen sections of various rabbit and human tissues by indirect immunofluorescence. Strong staining was observed in all stratified squamous epithelia (epidermis, cornea, conjunctiva, tongue, esophagus, vagina, and anus), in epidermal appendages (hair follicle, sebaceous gland, ductal and myoepithelial cells of sweat glands), as well as in Hassall's corpuscles of the thymus, indicating that all contain abundant keratins. No staining by the antiserum was observed in fibroblasts, muscle of any type, cartilage, blood vessel, nerve tissue, iris or lens epithelium, or the glomerular or tubular cells of the kidney. In contrast, the antiserum stained the cells of most epithelia of the intestinal tract, urinary tract (urethra, bladder, ureter, collecting ducts of kidney), female genital tract (cervix, cervical glands, uterus, and oviduct), and respiratory tract (trachea and bronchi). Epithelial cells of the fine ductal system in the pancreas and submaxillary gland also stained well. When primary cultures of epithelial cells derived from bladder, intestine, kidney, and trachea were grown on glass coverslips and stained with anti-keratin, fiber networks similar to those of cultured keratinocytes were observed. These results show that keratins constitute a cytoskeleton in epithelial cells of diverse morphology and embryological origin. The stability of keratin filaments probably confers the structural strength necessary for cells covering a free surface. Keratin staining can be used to obtain information about the origin of cell lines.

A case is presented in which massive uterine hemorrhage in early pregnancy is successfully controlled by bilateral uterine artery ligation. A 26-year-old white woman, gravida 3, para 1, abortus 2, was admitted 8 days following an elective abortion because of heavy bleeding and a low grade fever which failed to respond to Ergotrate and tetracycline. Although bilateral ligation is not the answer to all problems of bleeding from the uterus, it is superior to most other procedures, and physicians providing obstetric care should be familiar with the technique. The vessels can be easily identified, and the ureter and bladder are outside of the operative field. Although bleeding may continue from ovarian collateral vessels, the success rate is 90% with most of the failures being associated with placenta previa or placenta accreta. There are no short or long term complications.

This short survey presents some methodological aspects on intraluminal pressure recordings in vivo from the female urogenital tract. The importance of adequate calibration is stressed and a calibration unit for different types of recording equipments is described. Calculations of measuring errors are outlined. The selection of recording catheters is disucssed from both the theoretical and the practical point of view. Finally some practical aspects are considered on pressure recordings in vivo from the ureter, the bladder, the urethra and the uterus. This discussion is illustrated by pressure diagrams obtained with different recording techniques from the actual organs.

A survey is presented, based upon a personal material of 225 cases of urinary fistulae. 173 of them were postoperative or obstetric fistulae, whereas 52 had appeared after a radiological or combined radiological and surgical treatment for cancer of the uterus. --The author's method for preparing the fistula region from a transverse incision under the external urethral orifice is described as well as his grafting techniques. Vessels are brought to the fistula region by using flaps from one or both pubococcygeus muscles, the rectus abdominis muscle or the gracilis muscle. --For vesico-vaginal fistulae situated high up in the fundus a graft from the omentum majus or an appendix epiploica is sometimes used. They can usually be grasped from below after the peritoneum has been opened. --In cases where the ureters were also damaged by irradiation a special technique was used. After the damaged part of the ureter had been resected the ureters were implanted into an ileum segment which was anastomosed to the bladder fistula. --In one of the 173 non-irradiated cases, a Bricker-bladder had finally to be made because of the failure to achieve a functioning urethra. The others were all cured after one or in a few cases two operations. --Among the 52 cases, which had been irradiated, 46 coud to be made, one got a fast growing local recurrence of the carcinoma and one had too bad general condition to allow a diversion operation. Two patients have rest fistulae but may be possible to cure conservatively.

A study ia mde of 15 patients with a known neoplasia: 2 retroperitoneal tumours, 5 lymphomas, 3 prostate neoplasias, 3 seminomas and 2 uterus neoplasias; with displacement of the ureter and in some cases ectasia of the excretion system. The displacement was always one-sided and most frequently found in the lower third of the ureter. Ectasia was found in two patients; we have never found this in any patients without a known neoplasia. Adenopathies were the most frequent cause of inferior ureter deviation but in only one case did they infiltrate into the wall and they were more constant on the right side. These cases are compared with other patients suffering from different pathologies, some of which are also neoplastic but in which no displacement or ectasia appeared even when the retroperitoneum was affected, and with another group of patients in whom there was found to be ureteral displacement or ectasia without any retro- or intraperitoneal pathology.

We report on a rare form of bicornuate uterus with simple vagina and isolated hematocervix on right without connection of the right uterus to the vagina. Besides we found an aplasia of the right kidney and ureter. The case specially the isolated hematocervix and therapeutic problems of this double anomaly are discussed.

Immediately after birth, a full-term infant was noted to be in severe respiratory distress and died approximately five hours later, despite resuscitative efforts. Postmortem examination revealed agenesis of the trachea with a 1-mm fistula joining the esophagus and the main stem bronchi at the carina. The right kidney, ureter, Fallopian tube, and cornu of the uterus were also absent. The 25 previously reported cases of agenesis of the trachea are summarized, with special emphasis on associated abnormalities.

166 Women were investigated after 26 weeks of pregnancy, divided into 4 groups (normal pregnancy, after urinary tract infection, with cystopyelitis and with toxemia). Renography is a very sensitive method. Only 6,6% women had bilateraly normal function. Unilateral pathology was detected more often on the right side (17,6% versus 2,9%) and the damage was on the right side also more intensive (30% versus 8%), and present as early as in the 7. to 8. month of pregnancy. The damage of the secretion phase of the renogram in pregnancy is mostly sequal of the disturbed drainage following compression of the ureter trough varicosal veins and the pregnant uterus.

A total of 65 cases showing asymmetry of the pelvic ureters of greater than 1.4 cm for which no cause could be identified are presented. Only one was a male. The right ureter was situated more medially in 61 of the 64 females. Comparison of the characteristics of these patients with 51 females with symmetrical pelvic ureters revealed no differences except for a significantly more frequent left-sided position of the uterus in the asymmetrical group. Gross medial displacement of the right ureter in a female probably represents a normal variant in a large majority of patients.

1. Recordings have been made from ninety single afferent units in the hypogastric and lumbar splanchnic nerves of the cat. 2. The majority of units examined had properties similar to those previously described in the splanchnic nerve: they were slowly adapting mechanoreceptors with one to six punctate mechanosensitive sites distributed mainly along blood vessels as they approached the viscera in peritoneal ligaments; they had a wide range of mechanical thresholds and conduction velocities in the range 0.5-24 m s-1. 3. Receptive fields were found over the bladder base or its peritoneal ligaments or both, on the uterus or broad ligament or both, on the colon or mesocolon or both, and in association with the ureter, vas deferens, prostate or pelvic fat pads. 4. Discharges from afferent units associated with the bladder were investigated during spontaneous (or reflex) bladder contractions, passive distensions, and tetanic contractions induced by electrical stimulation of the sacral spinal cord. The mean spike rates of the adapted (tonic) discharges, observed during distensions and induced tetani, differed over part of the range of intravesical pressures examined. Their behaviour is discussed in relation to the concept of 'in series' tension receptors within the bladder wall.
